Cortina Upgrade: What You Need to Know

On April 19th, Usman Asim, a developer relations engineer at Ava Labs, tweeted to remind all Avalanche validators that the Cortina AvalancheGo version (v1.10.0) is now available and will be activated at 23:00 Beijing time on April 25th. Verifiers must update nodes before this date, otherwise they will not be able to process upgraded new blocks. Github information shows that the changes in the upgrade will take effect on the main website on April 25th at 23:00. Cortina upgrade will migrate X-Chain to run Snowman++consensus, which means the entire network has been migrated to a single consensus engine. The Cortina upgrade also introduced batch authorization rewards and increased the C-Chain gas limit to 1500 gas.

Avalanche will activate Cortina upgrade on the main network on April 25th, and the validator needs to update the node before that

The latest upgrade to the Avalanche network, the Cortina upgrade, is set to take effect on April 25th, and all validators are required to update their nodes before this date. In this article, we’ll take a closer look at what the Cortina upgrade entails, and what validators can expect from the new changes.

What is the Cortina Upgrade?

The Cortina upgrade, named after the Italian ski resort where it was conceived, is the latest in a series of upgrades to the Avalanche network. It aims to improve the efficiency and scalability of the network by migrating X-Chain to run Snowman++consensus, which means that the entire network will be running on a single consensus engine. This makes for better interoperability and faster transactions, while also reducing the overall complexity of the network.

What Are the Changes?

The Cortina upgrade brings several notable changes to the Avalanche network. Firstly, it will introduce batch authorization rewards, which means that validators who bundle several transactions together will be rewarded with increased incentives. This is designed to encourage validators to prioritize batching transactions together, which will help to speed up the network.
Secondly, the C-Chain gas limit will be increased to 1500 gas. This will allow for larger and more complex transactions, which will help to accommodate the growing demands of the network and keep pace with the needs of the users.

Why You Need to Update Before April 25th

It’s important for validators to update their nodes before April 25th, as failure to do so will result in the inability to process upgraded new blocks. This means that any validators who have not updated their nodes will be left behind, and their ability to participate in the network will be compromised.
To update your node, simply head to the Github page and download the latest version of the AvalanceGo software. Follow the instructions provided to complete the update, and be sure to double check that your node is synchronized with the network before the activation on April 25th.

Conclusion

The Cortina upgrade is a significant step forward for the Avalanche network, and brings with it a range of improvements and benefits for validators. By simplifying the network and streamlining the consensus engine, the network will become more efficient and scalable, and better able to meet the needs of its users.
So if you’re a validator on the Avalanche network, be sure to update your node before April 25th to take advantage of the new changes and stay ahead of the curve.
